Computer technology is leading to sweeping changes in how we can reason about groups in diverse cultures. These developments are inherently cross-disciplinary. They blend the behavioral and social sciences—fields such as political science, psychology, journalism, anthropology, and sociology—with technological fields such as computer science, computational linguistics, game theory, and operations research. There is a need to bring these cultures together to help forge a common understanding of principles, techniques, and application areas. That is the purpose of this conference.
